Danelectro puts the D-2 FAB Overdrive Guitar Effects Pedal in your hands without wiping out your financial portfolio. History was made in 1975 when a mom-and-pop store in California commissioned the production of just 200 of what is perhaps the best guitar overdrive effect ever. Unlike any other effects unit, that pedal authentically simulated the breakup that occurs when a tube amp is run at full volume. You will occasionally see an original in the stage rig of a major artist. IF you could find an original offered for sale, you should probably sit down before inquiring about the price . . .
